Were you referring to me or to someone else?...

It was aimed at anyone with an Intel card. We have also recently fixed a bug which we believe to be the cause of the "GL Error: 1282" errors - this will appear in the next playtest, which should be released sometime in the next week.

Problem is, that Intel claims that for my driver OpenGL works.

Or at least this is what it claims. Is there any test to see if OpenGL works?... I've got no settings to see if it actually works. Or even NET framework. I've tried as well what rami proposed, and it still doesn't work.

Try this (unofficial) test build: http://sleipnirstuff.com/openra/devtest ... 110625.exe

The game works, yet the editor doesn't.

Tho...what could be the problem with .NET framework then?...

With this build OpenRA gets as far as opening the window and showing the loading screen ('articulating splines, etc), before crashing again, showing the "this application needs to close'' dialog.

Contents of exception.log:

Code: Select all

System.InvalidOperationException: GL Error: GL_INVALID_ENUM
   at OpenRA.Renderer.Cg.GraphicsDevice.CheckGlError()
   at OpenRA.Renderer.Cg.GraphicsDevice.CreateTexture()
   at OpenRA.Graphics.Sheet.get_Texture()
   ...

Configuration:

Code: Select all

Graphics:
	Renderer: Cg
	Mode: Windowed
	WindowedSize: 640,480

With the GL renderer it crashes almost instantly with the following in exception.log (I've attached the full logs):

Code: Select all

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.InvalidProgramException: Unsupported GPU. See graphics.log for details.
   at OpenRA.Renderer.Glsl.GraphicsDevice..ctor(Int32 width, Int32 height, WindowMode window, Boolean vsync)
...

With graphics.log:

Code: Select all

Unsupported GPU: Missing extensions: GL_ARB_vertex_shader,GL_ARB_fragment_shader
...

Card: Intel GMA950 (945G)
Driver: 6.14.10.4926 (apparently the latest)
OS: WinXP Pro SP3 UK

Some random GPU caps viewer (kludx) suggests the card does indeed lack vertex shaders (but does have pixel shader 2.0 support). Anything else we can check / do?

@twarpie:

The 950 will be slow, but it should be capable of running OpenRA without crashing using the Cg renderer.

That `GL Error: GL_INVALID_ENUM' exception is definitely caused a bug - either in OpenRA, or in your drivers (which is still our problem - we should work around these issues, or at least test for them early and exit gracefully with a decent error).

We will add some extra debug logging into the next build, which should hopefully give a bit more information on what is causing this.

Yes, I assumed as much with regards to the performance of the GMA.

Is this going to be a 'release' build, or should I do a check out from git?

Seems the 950 does support

Code: Select all

GL_ARB_fragment_program
GL_ARB_vertex_program

just not

Code: Select all

GL_ARB_fragment_shader 
GL_ARB_vertex_shader

Perhaps the shaders could be converted / compiled / rewritten (not a shader expert here)?

This is what the Cg toolkit, used by our Cg renderer, does.

The fixes that I mentioned above will go into the playtest build that we intend on releasing in the near future. I may also release another unofficial test build with the fixes for people to try if the playtest is delayed much longer.

Ah right.

Ok. Will await the playtest then.

Thanks for all your effort btw, very nice project.

Just some further experimentation: placing the OpenGL32.dll from GLIntercept (source available) in the OpenRA directory allows OpenRA to run. Still using the Cg renderer.

Log file from GLIntercept logs a lot of INVALID_ENUM errors, but the game never crashes.

Obviously not a solution, or even a workaround.

Interesting... Could you please post the GLIntercept logs? They'll hopefully point us at the calls that are failing.

See attachments. Archive contains all logs (OpenRA & GLIntercept). GLIntercept was configured with the 'gliConfig_FullDebug.ini'.

The GL renderer crashes, Cg runs.

Any progress on this? Hope this doesn't come across as whiny: just anxious to play the game on my lacking gma950

OpenRA

...it doesn't work on Windows XP SP3?!!
